The brighter the ruby, the better?
The fluorescence effect of ruby will make the color of ruby more beautiful and shiny. The higher the content of chromium in ruby, the stronger the fluorescence effect, which will become more vivid in natural light, especially in the sun, and the vitality of ruby will be displayed to a greater extent. This is the fluorescence effect of gemstones. The fluorescence effect of rubies will make the appearance color more vivid, so when buying rubies, rubies with good fluorescence effect have higher prices. Of course, it mainly depends on personal preferences. After all, this difference is not obvious in the environment with less light.
Why doesn't ruby shine?
The fluorescence content in ruby is very weak. The brightness here actually refers to the fluorescence effect of ruby. Ruby contains an element that can convert ultraviolet rays in sunlight into its own light and luster. Some rubies contain less of this element, so they are not so bright. But no matter whether it is strong fluorescence or weak fluorescence, it will not emit light without light irradiation.
How to clean and brighten rubies?
Ruby jewelry can be soaked in mild cleaning solution for more than ten minutes, then cleaned with a soft brush and dried with a soft cloth. Bleach or detergent and toothpaste containing abrasives should not be used for cleaning. In addition, it is best to go to the jewelry store every six months to do a professional "beauty overhaul" to ensure that the luster of jewelry lasts forever. It should be noted that jewelry without borders or micro-inlays should not be cleaned by ultrasonic cleaning machine to prevent gems from falling off.
There are several conditions to pay attention to when choosing rubies.
1, granularity
The larger the particle size of ruby, the higher the price.
Step 2 crack
Because the cracks in rubies are common, we should try to choose rubies with few and thin cracks, especially rubies with cracks passing through the center of the gemstone.
3. Fire color
It is the color displayed on the front of ruby under the illumination of light source, which is essentially a reflection of the comprehensive effects of ruby transparency, cutting and color. When a good ruby rotates gently (the table is facing itself), you can see that there are many small red "flames" flashing inside, and it is required that the fire color of high-quality ruby should account for more than 55% of the total crown.
Step 4 color
Ruby has many colors, the best is deep pure red, followed by purplish red, followed by deep pink, purplish red and brownish red. Others, such as brownish red, black red and light pink, are inferior rubies. In addition, when observing rubies from the table, it is best to see only one color when rotating. If you can see other colors, it means that the ruby is not oriented correctly during processing.
